摘要

群组签名方案允许群组成员代表群组匿名签署消息。指纹识别方案通过向每个买家提供一个略有不同的版本，使商家能够识别非法分销的数字商品的买家。匿名指纹识别方案允许买家在不向商家透露身份的情况下购买商品。提出了一种高效的匿名指纹识别方案，该方案采用组签名方案。

Applications of group signatures to anonymous fingerprinting schemes

A group signature scheme allowed a group member to sign messages anonymously on behalf of the group. Fingerprinting schemes enable a merchant to identify the buyer of an illegally distributed digital good by providing each buyer with a slightly different version. An anonymous fingerprinting scheme allows the buyer to purchase goods without revealing her identity to the merchant. We propose an efficient anonymous fingerprinting scheme that uses group signature schemes.
